Same here. Mine also was not compatible luckilly I managed to install Windows 11 using rufus and it was working fine. I am using Intel Core I3, 4gb and just added 4gb recently fotal of 8gb of Ram. U cant upgrade your windows to 11 via updates. Only way is to install a fresh copy of windows and download your windows 11 from a reliable source and check hashes before and after you download the OS for safety.
